3,995,642 | 3,995,643 | Setters/getters and hierarchical data structures | <p>I know it is considered a bad idea to have public fields in your class. But what's the best approach when your class includes numerous hierarchical data structures and fields? For example:</p>
<pre><code>class A {B d1; C d2; D d3;}
class B {E d4; F d5;}
class E {G d6; int d7;}
</code></pre>
<p>In C it is quite easy to access such a data structure, e.g. ptr_to_A->d1.d4.d7 and so on... But what's the approach when we use setters/getters?</p>
<p>When using setters and getters in C++, expressions like A.get_d1().get_d4().get_d7() don't seem convenient, and they force returning references. Since some structures are pretty big, returning by value seems a terrible idea.</p>
<p>Which approach or coding style do you use in these cases? Maybe getting rid of setters/getters and making these fields public? </p>

4,814,254 | 4,814,255 | Which method is faster? | <p>I have a text file that serves as a simple database, each entry spanning two lines, like so:</p>
<pre><code>name
number
bob
39
jack
22
jill

</code></pre>
<p>Now say that I have each line separated in an array, and I wanted to analyze each NAME and see if it equals a variable. Would it be faster to do this:</p>
<pre><code>if($variable == $line) {
//true
}
</code></pre>
<p>Or first filter out the even numbered lines (the names), and then analyze them to see if they equal the variable? If you don't know, the first line following basically finds the remainder of the count (this is all in a foreach loop) divided by 2, and if it equals 0 then it is an even number.</p>
<pre><code>if ($count%2 == 0) {
if($variable == $line) {
//true

3,853,866 | 3,853,867 | How can I go through each link on a page and append something with jQuery? | <p>I have a bunch of links on a page that on an action, I run a function and it appends an extra variable like so:</p>
<pre><code>function storeId(uID) {
$('a.special').each(function(){
$(this).attr('href',$(this).attr('href')+'&variable='+uID+'');
});
}
</code></pre>
<p>My understanding is, the above would go through each link identified, and grab the existing href, then append the variable bits onto the end. I have got the variable appending, but its not working as expected... e.g its appending the '&variable=' part twice, the first time, like '&variable=undefined' and then on top of that '&variable=23'. </p>
<p>Is there a better way to do this? Or a way I can just say go through each of these links and simply update the value that is set to the variable rather than rewriting the whole href?</p>
<p>So just to re-iterate, my original link is just something like this:</p>
<pre><code><a class="special" href="/page.php?random=1">link name</a>
</code></pre>
<p>And the aim is to have it look like the following after the function is performed:</p>
<pre><code><a class="special" href="/page.php?random=1&variable=32">link name</a>
</code></pre>
<p>But it winds up looking like:</p>

if (lft > num) {

<p>The movement is fine. The problem I have is with stopping it, which is what this snippet does</p>
<pre><code> pp2.style.left = lft+"px";
if (lft > num) {
pp2.style.left = num;
</code></pre>
<p>When the num in (lft > num) and pp2.style.left = num is substituted with a real number, say 310, it works just fine. However when "num" is left in it does not stop. The reason I want to be able to substitute the stopping number is because I will have several buttons that will make the bar stop at various places on the site. I've been working on it for several hours and I've done everything I could think of. Hopefully you guys can do better than me! :)</p>

<p><strong>Possible Duplicate:</strong><br>
<a href="http://stackoverflow.com/questions/2356408/problems-with-nested-loops">Problems with nested loops…</a> </p>
</blockquote>
<p>I have 2 different dictionary programs that I want combined (or put together).<br>
The first one has the possibility to get good translation with grammar etc.<br>
Here is the code so far:</p>
<pre><code>words = {('i',): 'jeg', ('read',): 'leste', ('the', 'book'): 'boka'}
max_group = len(max(words))
sentence = "I read the book".lower().split()
translation = []
position = 0
while sentence:
for m in range(max_group - 1, -1, -1):
piece = tuple(sentence[:position + m])
if piece in words:
translation.append(words[piece])
sentence = sentence[position + m:]
position += 1
print(' '.join(translation))
</code></pre>
<p>In program 2 you can write more than just one sentence at a time.<br>
You will also get the first letter in a sentence capitalized.<br>
The third thing is that you get the word that isn’t in the dictionary printed out. </p>
<p>Here is the code for program 2:</p>
<pre><code>import re
words = {'i':'jeg','am':'er','happy':'glad'}
sentence =input('Write a sentence:')
sentence = sentence.split()
translation = []
for word in sentence:
piece = re.sub('[^a-z0-9]', '', word.lower())
punctuation = word[-1] if word[-1].lower() != piece[-1] else ''
if piece in words:
translation.append(words[piece] + punctuation)
else:
translation.append(word)
translation = ' '.join(translation).split('. ')
print('. '.join(s.capitalize() for s in translation))
</code></pre>
<p>So the question is: How could I use the best of each program
and just make a good one?...</p>
<p>I appreciate every good effort…<br>

<p>Basically, I have an object that I want to use as an array, but with some more properties. </p>
<p>I'm aware that there are other ways to extend Array, however I have been using this extend method throughout my code, so I would like it to be consistent.</p>
<p>I would like something like this, it's very awkward though:</p>
<pre><code>var Array2 = Class.extend(Array);
var Foo = Array2.extend(
{
init : function() {
}
});
</code></pre>
<p>EDIT: One of the major problems is that the 'length' property is not properly updated when you add something via index. I.e </p>
<pre><code>var x = new Foo();
x[0] = "test";
alert(x.length) //0

<p>What I want to do is to get all the numbers from the Act array and use implode to store it in a mysql db.
I tried array_keys but it doesnt work with multi-dimensional arrays. I dont know if it would be even appropriate for this. So basically I want an array with all the values of "Number" of $Story[1]["Acts"], so it would have to go through:</p>
<pre><code>$Story[1]["Act"][0]["Number"]
$Story[1]["Act"][1]["Number"]
$Story[1]["Act"][2]["Number"]
...
</code></pre>
| php | [2] |
